Abstract

Inhaled corticosteroids (ICS) are usually well tolerated with smaller systemic effects than intravenous steroids, however, when the dose is high the likelihood of steroid-related systemic side effects like hypothalamic pituitary adrenal (HPA) axis suppression and osteoporosis are reported. We reviewed HPA axis suppression related to different ICS characteristics by affinity to steroid receptor and their pharmacokinetics, and also reviewed by randomized, controlled clinical trials. Within the approved dosages for each ICS in Japan, HPA axis suppression is basically minimal and clinically negligible.

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
